I was in the process of trimming a bunch of 223 to make 300BO when I decided hand trimming wasn't for me. I already had a Lyman case trimmer with a full set of collets, so I ordered the conversion shaft to a drill/driver. Mounted it to a couple of boards to get it to the right height. It was cheaper than buying the hand held case trimmer for the different calibers I reload. It goes pretty quick.
If you want to deprime a bunch of brass whilst sat on the couch: Home Page
- No need to size pistol brass. Anything being sold to do so is a waste of money.
- Try to keep batches of reloadable brass separate for the rifle they were originally shot from. Neck size only, and your cases will last longer.
- I have found that a 75% powder load of the MAX charge is usually the most accurate, and efficient out of Semi-autos.
Gotcha.Ok. Let me elaborate.
A few notes:
- No need to TRIM pistol brass. Anything being sold to do so is a waste of money.
- No need to crimp 9mm or .45 acp. Case headspaces to the rim of the case. Anything being sold to do so is a waste of money.
